Common Mist Frog

Range and abundance

The Common Mist Frog is endemic to the wet tropics rainforests of north-east Queensland between Ingham and Cooktown. During the 1990s, the Common Mist Frog disappeared from high elevation rainforests across most of its range.

Description

The Common Mist Frog is 3 – 4 cm long. Individuals are grey, brown or green, often with a distinct pale roughly triangular patch on the top of the head. The skin on the back varies from smooth to rough. The eye is often chestnut brown, and the belly is cream to pinkish. The finger and toe pads are large with distinct webbing.

Ecology

Common Mist Frogs can be found on rocks and vegetation within or next to relatively fast-flowing streams in rainforest and wet sclerophyll forest, where they feed on a wide range of invertebrates. Their call is a drawn out “wreeek, wreeek, wreeek”. The tadpoles live in the fast flowing water, using their muscular tails to negotiate the current and their large suction-like mouths to grip onto rocks and graze on algae.

Threats

The introduced pathogen Chytrid Fungus (Batrachochytrium dendrobatidis) is a probable cause of the decline of upland populations of the Common Mist Frog, as for other rainforest frogs. Populations at lower altitudes now appears to be stable, and recent discoveries suggest populations may be recovering at high altitudes. Alluvial mining may threaten local populations by causing loss of habitat and fouling of streams from sediment, heavy metals or other contaminants.


 

What is AWC doing?

AWC protects the rainforest habitat of the Common Mist Frog on Brooklyn. AWC ecologists monitor populations of the Common Mist Frog and other rainforest frogs on streams on Brooklyn. The monitoring program aims to determine whether remaining frog populations are stable, and whether frogs will re-populate higher altitude streams. 

Did you know:

Males of the Common Mist Frog display a ‘foot-flagging’ behaviour where they wave their feet in the air, perhaps to communicate with other male frogs. This behaviour may have evolved because frog calls can be barely audible in rainforest streams, obscured by the noise of rushing torrents of water.
